Fujita cold air intake 1904
 

im new to the forum been looking and reading but cant find anyone who has installed a fujita cold intake on a 1999 honda civic ex. Im having a hard time finishing up the installation, i have the CAI installed and mounted but i have a loose hose that is letting out alot of air. On the fujita instructions is tells me to unplug the coolant hoses and replace them with the one provided. Is there a reason why i should replace it or can i just leave it the the stock one on ? also tells me to remove vaccumm hoses. thanks in advance
